5.4-GHz AP Cluster Recommended Channels
The fully populated cluster requires only three channels, each reused by the module that
is mounted 180° opposed. In this frequency band range, the possible sets of three non-
overlapping channels are numerous.
IMPORTANT!
Where regulations require you to have Dynamic Frequency Selection
(DFS) enabled, analyze the spectrum, then spread your channel
selections as evenly as possible throughout this frequency band range,
appropriately sharing it with satellite services.
12.3.6 5.7-GHz Channels
Channel selections for the AP in the 5.7-GHz frequency band range depend on whether
the AP is deployed in cluster.
5.7-GHz BH and Single AP Available ISM/U-NII Channels
A BH or a single 5.7-GHz AP enabled for ISM/U-NII frequencies can operate in the
following channels, which are separated by 5-MHz increments.
(All Frequencies in GHz)
5.735 5.765 5.795 5.825
5.740 5.770 5.800 5.830
5.745 5.775 5.805 5.835
5.750 5.780 5.810 5.840
5.755 5.785 5.815
5.760 5.790 5.820
The channels of adjacent APs should be separated by at least 20 MHz. However,
25 MHz of separation is advised.
5.7-GHz AP Cluster Recommended ISM/U-NII Channels
Six non-overlapping ISM/U-NII channels are recommended for use in a 5.7-GHz AP
cluster:
(All Frequencies in GHz)
5.735 5.775 5.815
5.755 5.795 5.835
The fully populated cluster requires only three channels, each reused by the module that
is mounted 180° offset. The six channels above are also used for backhaul point-to-point
links.
As noted above, a 5.7-GHz AP enabled for ISM/U-NII frequencies can operate on a
frequency as high as 5.840 GHz. Where engineering plans allow, this frequency can be
used to provide an additional 5-MHz separation between AP and BH channels.
